The piece that is chrome/satin chrome or whatever will fit. The black plastic piece will not. You can separate the black piece if it is like the plain gills and it should fit. But, if it doesn't separate then no it won't work. AFAIK, there's no reason that the grills should not work.

Cheers.

Thanks for the reply - i have seen a DIY of the E90 side gill and the chrome part definately separates from the plastic piece - i should have been more specific, my concern was that the chrome part was different in some way from E92 to E90....longer etc etc. If they are the same then i will order mine tommorrow
